TYPE-'WRITING MAC HINE,

Specification of Letters Patent. Patented-June 1913 Application filedJanuary is. 1913. Serial no. 742,341.

:Beitikiimvn that I, HERBERT H. SrEELn, citizeirof the United States,and resident of Marcellus, in'the county of Onondaga and State of NewYork, have invented certain new and useful Improvements in Type-WritingMachines, of which the following is a specification.

My invention relates to type-writing machines and more particularly totabulating mechanism. 1 One of the objects of' my invention is to.provide a comparatively simple and efficient two-way tabu'lator' bywhich a tabulating' operation may be effected by a backward movement ofthe carriage, as well as by a forward movement thereof in the directionof its feed. Another object of my invention is to provide novel means bywhich the carriage may be arrested at the same letter space position,whether a backward or forward tabulation is effected. I

A further object of my invention is toprovide novel means for holdingthe carriage-againstmovement which would tend to separate the tabulatorstops when an arrest of the carriage isefi'ected by said stops.

A still further'object of my invention is to provide means of thecharacter specified above that may be readily embodied in existingstyles of typewriting machines without modifying, or materially modif s'ing the structural features of said machines as they 35.

now exist.

To the above and other ends which w ll hereinafter appear, my inventionconsists one of the. denominational stopsand its ass ci-ated latch.'Fig. 4 is a fragmentaryplan view, .withparts. in section, the Viewshowing a portion of the tabulator mechanism and some of the associatedparts. Figs. 5 and 6' are enlarged detail diagrammatic plan views of thetabulator stops. Figs. 7 8, 9 and 10 are fragmentary diagrammatic feedpinion and feed rack, the different views showing the parts disposed asthey appear under different. conditions of use.

I have shown my invention embodied in the present instance in' theMonarch machine in which the invention may be readily included withoutmodifying, or materially modifying, the structural features of thatmachine as they now exist. It should be understood, however, that theinvention may ing machines.

base 1, corner posts 2 and top plate The carriage comprises a cross orslide bar 4 from which end bars 5 project forwardly to support a rotatie platen 6. The slide friction balls or rollers wluch are received inoppositely grooved guide ways in the slide bar, and are also received inoppositely grooved guide rails i fixedly supported on the top plate ofthe machine, so-that the carriage may travel from side to side of themachine over the top plate.

Upwardly and rearwardly striking type bars 7 are segmentally arrangedand the platen. These type bars are connected .to sub-levers 8 byintermediate actuating links 9. Each sub-lever 8 is pivoted at 10 to akeylever 11 which is fulcrumed'at its upper rear edge portion against afulcrum plate 12 and extends forwardly to the keyboard of the machinewhere it provided with a finger key 13.'

A universal bar 14 extends beneath the series of key levers and iscarried by a frame 15 formed with a rock shaft 16 which is pivoted inthe base of the machine. A

this frame and is connected to an upwardly extendmg lmk 18 which m turnis connected t -o a forwardly pro ecting arm 19 of The frame of themachine comprises a adapted to strike against the front face ofrear'wardly projecting arm 17.eXte-n ds from a dog rocker 20. This dogrocker is pivoted at 21 to a bracket 22 secured to the-top pl atc of themachine.- The upwardly extending views of certain of. the tabulatorstops, the

be embodied in various styles of typewrit-- bar't of the carriage issupported by antiarm of the dog rocker carries teed dogs 23 whichcoilperate with an escapemcnt wheel V end of the escapeinent wheel shaltcarries a feed pinion 26 with winch a feed rack 27 meshes. The feed rackis supported by arms 28 pivoted at 29 to the carriage. Returning springs30 are connected with the key levers and the parts connected therewithto return them to normal position after the keys have been depressed,and a returning spring 31 is eii'ective to return the dog rocker andassociated parts to normal position.

Curved bracket arms 32 are supported on. the top plate of the machineand constitute supports for the fixed guide rails 4. Rearwardlyprojecting bracket arms 33 extend-from the carriage in line with theopenings in the curved bracket arms and con stitute supports for acolunnrstop bar 34-. This stop bar has teeth projecting from the frontand rear sides thereof for the reception of bifurcated flatsheet metalcolumn steps 36 in the interdental spaces between the teeth 35. Thecolumn stops are thus held against lateral play or movement on thecolumn stop bar and in the dihterent positions to which they may beadjusted along the bar. A tabulator frame 37 is fixedly connected to theframe of the machine in the usual manner by screws 37 and supports a.

pivot rod on which donominational stop carrying levers 39 are pivoted,said levers extending forwardly at the upper ends thereof to formdenominational stops l0. These denominational stop levers and the stopscarried thereby are maintained spaced apart by devices ll which in thepresent instance constitute latching means or devices, as willhereinafter more clearly appear. The lower end 42 of each denominationalstop lever co-acts with a slide bar 3 which extends, and guided formovement, fore and aft of the machine. Each slide bar, at its forwardend, meets with a depending crank arm Mr. fixed to a rock shaft 45 supported in upwardly extending bracket arms 46. Each rock shaft 43 has aforwardly extending arm l7 fixed thereto. the arm carrying adenominational kev 48 at its forward end. It will be understood.therct'ore. that a depression of a denominatiomil kev is effective tomove the associated bar rearwardlv, thercb transmitting a pivotalmovecolumn stops 31' The usual returning springs l9 cooperate v t3: the(ltllflllilllib' tional stop h -"rs to return the r: and the m). 1*.universal her 0 extends across -frame 37. One of the arms 51 is extendedLoeeeea the series of denominational stop levers 39 V at the rearthereof and below the pivot v3S. T his universal bar is supported onarms 5i which are pivoted at 5:2 to the tabulator forwardly Wherepivotal connection is made at with an up *ardly extending link 541 Theupper end of this link '54:. is connected to a lever pivoted {it-5h to adepending bracket 57 which extends from the top plate 3 of the machine.One end of the lever is bent upwardly to form a stop 58 which cooperates with the top plate of the machine to limit the movement of theparts in one; direction. The opposite end oi. the lever 55 is pivoted.at 59 to an upwardly extending carriage releasing device (30 guided inits vertical movement by the escapement wheel shaft 61. Contact shoes(32 project forwardly from the releasing device and extend so that aneleva- S5 beneath the feed rack tion of the releasing device (30 fromthe position shown in Fig. 2 is effective to elevate the feed rack anddisengage it from the feed pinion. It will be understood, therefore,- 0that a release of the carriage is effected at ach actuation of adenominational stop as the latter is projected into'the path of thecolumn stop, and that at' such time the can riage is-free to be movedfrom right to left 9 under the power of its spring drum (33 which isconnected to the carriage in the usual manner. v r

The construction thus far described is similar to that embodied in theivlonarch machine except that the spacing devices: ll. usually employedin the Monarch machine are of a ditlerent character from those shown inthe accompanying drawings. the. usual spacing devices not being in thenature of latching means or device-=. In the present instance 1substitute for the oidinar spacing means employed between thedenominational stop lovers :1 series of latching devices ll whichconform substantially in outline to the upper portions of thedenominational stop lovers. the latches l] terminating at their lowerends at it. These ltllt'llQH alternate with the denominational stops andare pivoted on the pivot rod 38 for movement fore and aft of the machinein the same general direction as the dcnominaiional stops. As will beseen more clearly from an inspection of Fig. -1, each of thedonominaticnal stops 0 has a laterally extending pin or proje tion ('35extending*lroui the back face theinol l refer to the back face of eachdonominational stop to distinguish it from the front face ('16 oi thestop with which the column stops ')-Htl ata hu ward- 125 talndatngoperation citcctodduring the fl travel of the earring? from rightlo-ictt-i'n in the direction of its feed. l hn'h pin or oje tion (33 isreceived in a slot or opening UT in the adjacent left-hand latch 41.This 130 opening or slot is of a' sutiicientextcnt to aiford'a limitedindependent movement neof Fig. 1, each latch 41 has fixedly con-'vnected thereto, and projecting from its lower -edge,-a depending wirespring68, the lower tween the latch, 41 and its associated dehereinaftermore clearly appear.

As will be understood from an inspection nominational stop, for purposeswhich will end of which is bent to engage around the rear edge oftheassociated denominational stop lever 39. The power of each spring 68 71S exerted to force the associatedlatch for-' wardly until it isarrested by the rear Wall of the slot 67 therein engaging the pin orprojection on the associated denominational stop, as shown in Figs, 1and 3.

Each spring 68 therefore tends to normally nainta'l'n this relationbetween a latch and its associated denominational stop. .It will.

- be seen that-each latch is locatedon the back or left-hand side. ofthe associated denomi-.

sto-psetO and series of latches 41 are arranged adj acentone another andoccupy a space he'-- tween a contact edge 69 and a contact edge 70 of afront plate 71 fixed to the tabulator frame. The-contactedges69 and 7 0resist a n 1ovemei1t of the .stops and latches inop p'osite' directions.An adjusting screw .72" is received in a tapped opening in the left;

hand side of thejtabula'tor frame 37 and bears at its inner end againsttheleft-hand "latch 41, as shown in Fig. 4. This screw is 'efi'ective totake 111a any undue v play or lateral motion between the series ofdenominational stops and the-series of latches t1, although these partsare rather loosely disposed in the frame to provide suflicien't freedomof fore and aft movement between the parts.

- Ina forward tabulating movement 'the l parts co-actin the usual mannerandthe denominational stops, through their front contact-faces 66,co-act with the front faces 36? of the column stops 36 to arrest thecarriage. As will be understood from an 'inf7 in spection, of Figs. 7and 8, a movement-of a denominational stopinto operative position iseifectlve to'release the carriage by disengaging the feed raclt 27 fromthe feed pini n 26.- At the time that'the carriageis ari ted in itsforward movement by the co- 0]')1'z-."l0l1- of a column stop with thepro jected uencminational stop 40; the partsappear as represented inFig. 8. On a com 'parison of this figure with Fig. 7, which shows thepositions of the parts after'the denominational stop has been withdrawnfrom its projected position shown in Fig.

-8, ittwill he seen that the movement of the feed rack back into meshwith the feed pinion from the Fig.8 to the F ig. 7 positioni willafi'orda drop -of the carriage for a distance correspondingsubstantiallyto the has no particular effe'cton' the operation'of thetabulator in theor'dinary tabulatini-oo eration in' which the carriagemoves rom right to left to the point'of arrest except that it' enablesthe-stops to clear one an other, as will be understood from aninspecvtion of Figs. 7 and 10. It will be seen from a consideration ofthese figures that if the actuated after-a drop has been effected andthe parts are positioned as shown, then the projected denominationalstop is in aposition-to co'-act' with the next succeeding column stop,as it is-intended it should.f This clearing of the stops, therefore, is

efi'eetedby the drop scribed above.

In the operationof the devices. for reverse vor backward tabulation,denominational key is depressed, thereby projectingthecorrespondingdenominational stop forward with its rear face presented for cooperationwith the rear face .of the first'co'lumn stop of the carriage deto theleft." The operator then moves the carriagetothe right with onehand,lwhilemaintaining the denominational key de pressed with the other,until the'carriage 'is arrested by the cotiperatio-n of the. rear faceofthe first columnstop with the rear face ofthe projected denominationalstop. 7 During thismovement of the parts the beveled:

face/T3 of the column stop co-acts with the 1 beveled face'74 of'theprojectedlatch 41 ,as shown in Fig. 5, and forces the latch rearon theprojected latch, the spring-68 of said latch is effective to move itforwardly on a-rdly around its pivot against the forceof'. I i I thespring 68 of the latch. As soon" as-the column sto'p'has cleared thebeveled face 74: r I l the"left-hand "side or back of the column stop,as shown-in Fig? 6. This locks the "column stop and-projecteddenominational stop together, preventing a movement'of the carriage inthe direction of its feed, it being uniderst-oo-d 'that the feed rack ismaintained released at this time by. the depression of b thedenominational key. The carriage being held at this time, as shown in Figl 6, by the engagement of the latch 41 with the column. stop, saidlatch will restrain the carriage against movement in the direction ofits feed, and Willi-stain it'in the same letter space position that 'thecarriage Would-be arrested in by the coiiperat-ion of the samedenominational stop with the. same column stop in a. final arrest of thecarriage by ,a forward tabulation, through the lmovement' of thecarriage from right to left ThlS is thickness 'of one of thedenominational or f column stops. This drop of the carriage 80" I samedenominational stop 1s,1mmed1ate1y "due to the fact that in the tortvardtabulationthe carriage receives a drop from u in Fig.

vided during the reen'gagement of the rack andxpinion during the forwardtabulation.

Fig. 7 shouts the parts asthey appear 7 after the-arrest of thecarriage-during a .out depart forwardtabulation ,'whereas Fig. '10 showsthe parts as they appear after an arrest of the carriage effected bya'backward tabula 7 tion. It Will'be'seenthat in each case thedenominational stop 40 and the column stop. 36 bear the same relationsothat in" each instance the'carriagc is arrested at the same letter spaceposition assuming of course that the same denominational stopis.employed to co-actwvith the same column stop. Inone case the frontfacesof the'denomination-aldand column'stops co-act to arrest the carriage,although the final position of the carriage atthis time is not attaineduntil the denominational stop is Withdrawn and the drop of thecarriagehas been effected. In the other case the rear faces of the.denomi-natio-nal colmnnstops co-act to -arrest the carriage and thereis no such drop of the carriage rem this position of arrest; U.
